Layout and performance of the power electronic converter platform for the VSYNC project

Abstract

This paper presents the power electronic platform used for the VSYNC project. In this project, inverters are controlled in such a way as to exhibit a virtual rotational inertia towards the grid, in order to limit grid frequency variations in grids containing a high share of inverter-connected DER. First the layout and operation of the platform are described in detail, showing its versatility for research purposes. Next the performance of the platform is illustrated using experimental results obtaining using a grid-connected inverter in a laboratory setup.Index Terms-Virtual synchronous generator, power electronic converter, rapid prototyping platform, grid-connected inverter, virtual rotational inertia.

Notice of Violation of IEEE Publication Principles: LFC by coordinated virtual inertia mimicking and PEVs in power utility with MW-class distributed PV generation

“…Since the fundamental concept of VSMs was formally introduced, it has been subject of several publications. Most of the research deals with specific issues on the implementation of VSMs such as: the necessary requirements of the PEI to perform a VSM [3], selection of the storage media [4], laboratory prototypes for experimental tests [5] and an optimal virtual inertia controller for wind generator [6].…”

Comparison of multiple power amplification types for power Hardware-in-the-Loop applications

“…In this configuration a common neutral is used both for coupling to the utility grid and for the voltage source operation (Figure 3). A common mode choke and a feedback path between the filter and the DC link are used to mitigate the common mode current [6]. The switching frequency of the converter is 8 kHz, which is equal to the sampling frequency of the control unit.…”

Real time simulation of a power system with VSG hardware in the loop

“…Here, both DC to DC and DC to AC have bidirectional power handling capabilities. The power processor [9] from Triphase fits the VSG description due to the layout of its power electronic components as it shown in Fig. 5.…”

“…The power processor from Fig.1 is built from a Triphase ® [9], [10] inverter system. The Matlab/simulink VSG algorithm is directly implemented on the inverter system through a dedicated FPGA interface developed by Triphase ® .…”
